教学过程
(一)热身导入:情境唤醒,激活已知
1. 情境创设:教师展示社区志愿活动图片(如养老院帮扶、社区清洁、爱心捐赠),用简单英语提问:“Do you know these people? What are they doing? Do you want to help others like them?” 引导学生自由发言,用简单的英语或中文表达自己对志愿活动的认知。
2. 词汇铺垫:结合学生发言,自然引出本节课核心话题“Making a Difference”,并板书主题,随后呈现3-4个与志愿活动相关的简单词汇(如help、volunteer、kind),引导学生认读,回顾已学知识,为新课词汇学习做好铺垫。
3. 导入过渡:教师总结:“These people are volunteers. They do small things but make a big difference to others. Today we will learn some new words and phrases to talk about volunteering and making a difference.”
设计意图:通过真实的志愿情境创设,激发学生的学习兴趣和情感共鸣,让学生快速融入“奉献、助人”的主题氛围;同时激活学生已学相关词汇,降低新课词汇的学习难度,实现新旧知识的自然衔接,培养学生的语言运用意识和情感态度。
(二)词汇新知讲授:多维突破,夯实基础
本环节聚焦Section B Vocabulary in Use核心词汇(success, successful, succeed, medical, medicine, elder, elderly, volunteer, community, charity, sign up, make a difference, provide aid, clean up, be worth the effort),采用“音—形—义—用”四阶教学法,结合语境、辨析、练习,帮助学生扎实掌握词汇。
1. 核心词汇讲授(分簇推进)
第一簇:同根词(success, successful, succeed)
- 发音与拼写:教师示范每个单词的发音(/səkˈses/, /səkˈsesfl/, /səkˈsiːd/),强调重音位置和发音差异,引导学生跟读、齐读、个别读,纠正发音错误;同时板书单词,标注拼写规则(success n. → successful adj. → succeed v.),帮助学生记忆词形。
- 词义辨析与语境运用:结合志愿主题,给出例句帮助学生理解词义:① His volunteer work is a great success.(n. 成功)② He is a successful volunteer.(adj. 成功的)③ He succeeds in helping many old people.(v. 成功做到);随后提问学生:“Can you make sentences with these three words? Try to talk about volunteering.” 邀请2-3名学生发言,教师点评并补充,强化学生对同根词词性和用法的区分。
第二簇:医疗与年龄相关词汇(medical, medicine, elder, elderly)
- 情境关联:展示医院、养老院图片,提问:“What do we need in the hospital? Who do we help in the nursing home?” 引出medical(adj. 医疗的)、medicine(n. 药物)、elder(adj. 年长的;n. 长辈)、elderly(adj. 年老的,年迈的)。
- 用法讲解:重点区分elder与elderly的差异——elder常作定语,修饰人(如elder brother),或作名词指长辈;elderly侧重“年迈的”,语气更委婉,可修饰人(如elderly people),常用搭配the elderly(老年人);medical作定语(如medical help, medical examination),medicine为名词(如take medicine, give some medicine)。
- 即时练习:让学生完成简单的词性转换和选词填空:① We need ______ help for the sick people.(medical/medicine)② My ______ sister works in a hospital.(elder/elderly)③ The doctor gave him some ______ for his throat.(medical/medicine),集体核对答案,讲解易错点。
第三簇:志愿相关词汇与短语(volunteer, community, charity, sign up, make a difference, provide aid, clean up, be worth the effort)
- 词汇讲授:结合志愿场景,逐一讲解词汇和短语的含义及用法:volunteer(v. 自愿做;n. 志愿者),搭配volunteer to do sth.;community(n. 社区),短语in the community;charity(n. 慈善机构),搭配charity organization;sign up(报名参加),搭配sign up for sth.;make a difference(有影响,起作用),强调“微小行动带来的改变”;provide aid(提供帮助),同义短语provide help;clean up(清理,打扫),搭配clean up the community;be worth the effort(值得付出努力)。
- 例句示范:教师结合具体场景给出例句,让学生直观理解用法:① Many students volunteer to help the elderly in the community. ② She signed up for the charity activity. ③ Even small actions can make a big difference to others. ④ Cleaning up the park is worth the effort. 引导学生跟读例句,体会词汇和短语在语境中的运用。
2. 词汇巩固:小组接龙游戏
将学生分成4-5小组,每组依次接龙,要求用本节课所学词汇或短语说一个句子,句子需贴合志愿主题,不能重复。若小组无法及时接龙或句子错误,可由其他小组补充,最后评选“最佳词汇运用小组”,给予口头表扬。
设计意图:采用分簇教学的方式,将词汇按主题和规律分类,帮助学生建立词汇网络,降低记忆难度;结合情境、例句和辨析,让学生在语境中理解词汇用法,而非孤立记忆,培养学生的词汇运用能力;小组接龙游戏既能活跃课堂氛围,又能即时检验学生的词汇掌握情况,强化记忆,同时培养学生的合作意识和语言表达能力。
(三)词汇运用:语境迁移,提升能力
本环节结合教材Vocabulary in Use相关练习,设计分层任务,让学生在练习中巩固词汇,实现从“掌握”到“运用”的过渡,同时融入核心素养的培养。
1. 基础练习:语境填空(贴合教材2b题型)
呈现短文填空,短文围绕“Harry的志愿故事”展开,包含本节课所有核心词汇和短语,让学生根据句意和提示,填写合适的词汇或短语,注意词性和形式变化。
短文内容:Eleven-year-old Harry wanted to help out his ______ (community). He and his mum ______ (sign up) with a local ______ (charity) organization two years ago. He often helps the ______ (elderly) people with their housework and provides ______ (aid) for them. His volunteer work is a great ______ (success). He is ______ (successful) in making a difference to others. Harry says volunteering ______ (be worth the effort) because it makes him happy. Every weekend, he also helps ______ (clean up) the community park.
学生独立完成后,小组内核对答案,教师针对易错点(如sign up的过去式signed up、be worth the effort的主谓一致、elderly的用法)进行讲解,强调词汇在语境中的灵活运用,提醒学生注意词性转换和时态变化。
2. 提升练习:句型转换与造句
(1)句型转换:给出句子,让学生根据要求转换句型,巩固同根词和短语用法。例如:① His volunteer work is a great success.(改为形容词形式)→ His volunteer work is very successful. ② He succeeds in helping others.(改为同义句)→ He is successful in helping others. ③ They signed up for the charity activity.(改为一般疑问句)→ Did they sign up for the charity activity?
(2)主题造句:让学生结合自身实际,用“make a difference, volunteer to do sth., sign up, be worth the effort”中的至少2个短语造句,表达自己对志愿活动的看法或打算。例如:I want to volunteer to help the elderly because I want to make a difference to their lives. / I will sign up for the community clean-up activity. It is worth the effort.
邀请学生分享自己的句子,教师点评,肯定正确用法,纠正错误,鼓励学生大胆表达,同时引导学生树立“乐于助人、奉献爱心”的意识。
3. 拓展练习:语篇补全(贴合教材2c题型)
呈现一篇不完整的短文,主题为“社区志愿活动招募”,让学生运用本节课所学词汇和短语,补全短文,使短文意思连贯、语法正确。
短文内容:Do you want to ______ (make a difference) to your community? Join our charity organization! We need volunteers to help the elderly and children. You can ______ (volunteer to do) many things: help the elderly take medicine, clean up their houses, or teach children English. If you are interested, please ______ (sign up) for our activity. Your help will be ______ (worth the effort). We believe that with your help, our community will become better. Let’s work together to achieve ______ (success)!
学生完成后,邀请2-3名学生展示自己的补全内容,教师进行点评,重点关注词汇的准确性和语篇的连贯性,引导学生学会在语篇中整合运用词汇,提升语言组织能力。
设计意图:分层练习遵循“基础—提升—拓展”的逻辑,贴合学生的认知规律,让不同层次的学生都能获得成就感;练习内容紧密围绕志愿主题,既巩固了词汇用法,又强化了学生对“奉献、助人”的理解,实现语言能力与情感态度的协同发展;语篇补全任务培养学生的语篇意识和逻辑思维能力,为后续的阅读和写作奠定基础。
(四)巩固拓展:主题探究,深化理解
1. 小组讨论:围绕“如何用微小行动影响他人”展开讨论,提问:“What small things can we do to make a difference in our daily life? How can we use the words and phrases we learned today to talk about these things?” 给学生5分钟时间小组讨论,要求每个小组至少提出3个具体行动,并运用本节课所学词汇或短语进行表达。
2. 小组展示:每个小组推选1名代表,分享小组讨论的结果,例如:“We can volunteer to clean up the classroom after school. It is worth the effort. We can also help our classmates with their English. This can make a difference to them.” 教师针对学生的表达进行点评,补充合适的词汇和短语,鼓励学生大胆运用所学知识,同时引导学生认识到“微小行动也能带来大改变”,培养学生的社会责任感。
3. 词汇拓展:补充与志愿相关的延伸词汇(如kindness, help, care, donate),引导学生联想记忆,丰富词汇储备;同时总结本节课所学词汇的记忆方法(同根词记忆法、语境记忆法、主题联想记忆法),帮助学生掌握科学的词汇学习策略,提升学习能力。
设计意图:小组讨论和展示活动,既能让学生在交流中巩固词汇用法,提升语言表达能力,又能培养学生的合作意识和思维品质;主题探究深化了学生对“Making a Difference”的理解,将语言学习与情感教育、社会责任教育结合起来,落实文化意识和情感态度的培养;词汇记忆方法的总结,帮助学生掌握自主学习的技巧,提升学习能力。
(五)总结回顾:梳理知识,强化记忆
1. 师生共同回顾:教师引导学生一起梳理本节课所学的核心词汇、短语及用法,重点回顾同根词(success, successful, succeed)、elder与elderly的辨析,以及make a difference、sign up等短语的搭配和用法,通过提问的方式检验学生的掌握情况,如:“What are the three forms of ‘成功’? How do we use ‘elder’ and ‘elderly’? What does ‘make a difference’ mean?”
2. 学生自主总结:让学生用1-2句话总结本节课的收获,例如:“Today I learned many words and phrases about volunteering. I know how to use them to talk about making a difference.” 邀请几名学生发言,教师补充完善,帮助学生构建完整的知识体系。
3. 情感升华:教师总结:“Volunteering is a great way to make a difference. Every small kind action can help others and make our world better. I hope you can use the words and phrases we learned today to talk about volunteering and try to do something helpful for others.”
设计意图:总结回顾环节帮助学生梳理本节课的核心知识,强化记忆,避免知识碎片化;学生自主总结培养学生的归纳总结能力和自主学习能力;情感升华环节进一步深化学生对志愿精神的理解,落实情感态度与价值观目标,实现语言学习与人文教育的融合。
(六)作业布置:分层落实,延伸运用
1. 基础作业:抄写本节课所学核心词汇和短语(每个单词、短语抄写3遍并默写1遍),完成课后基础练习题(语境填空),巩固词汇记忆和基础用法。
2. 提升作业:用本节课所学词汇和短语,写3-5句话,描述自己的一次志愿经历(或想象中的志愿经历),要求语法正确、语句通顺,至少运用3个核心词汇或短语。
3. 拓展作业(选做):制作“志愿词汇海报”,画一幅社区志愿场景,用英语标注相关词汇、短语和句子,下节课在班级展示;或参与一次社区志愿活动,用本节课所学词汇写2句话记录自己的经历。
设计意图:分层作业兼顾不同层次学生的需求,基础作业巩固词汇记忆,提升作业强化语言运用能力,拓展作业激发学生的学习兴趣和实践能力;作业内容与志愿主题结合,让学生在实践中运用所学知识,实现“学用结合”,同时进一步深化对志愿精神的理解,延伸课堂教学效果。
